PROBLEM TO BE SOLVED: To provide a technology achieving miniaturization of an actuator and improvement of position detection accuracy of a movable sheave.SOLUTION: A sensor 60 is accommodated and arranged in a transmission case 28 as a body separated from an actuator 30. Thereby, miniaturization of the actuator 30 can be achieved. Also, as a displacement amount of an arm 26 is detected by the sensor 60, arrangement of the sensor 60 in the transmission case 28 can be freely designed according to a shape of the arm 26, and dead space in the transmission case 28 can be utilized effectively. Furthermore, as the displacement amount of the arm 26 which moves integrally with a movable sheave 21 is detected by the sensor 60, influence of a dimensional error and an assembly error of each element to the movable sheave 21 can be reduced, and the position of the movable sheave 21 can be detected with good accuracy. |
